omap_l138 bios实时性能否做到100us

以I2C驱动为例，Interrupt mode:
Bus Frequency                     Time Taken                    Throughput                  CPU LOAD
(KHz)                                       (milli-sec)                        (Kbps)                             (%)
100                                           0.32                                  60.66                              14.70
200                                           0.18                                  109.73                            26.08
400                                           0.11                                  180.29                            43.60
